CA 2206666
In order to improve the metering accuracy, especially with a strongly fluctuating feed material supply, a method and an apparatus for continuous, gravimetric metering and mass flow determination of flowable materials are proposed, wherein the output of the metering device (8) is regulated with a time offset to match the set-point flow rate in dependence on the instantaneous mass flow determined at the flowmeter (4).
L'invention concerne un procédé et un dispositif assurant un dosage gravimétrique continu et une détermination du débit massique de matières coulantes, et permettant d'améliorer la précision de dosage, notamment en cas de fortes fluctuations dans l'alimentation en matières transportées. A cet effet le débit de l'unité de dosage (8) est réglé avec un décalage dans le temps pour être adapté au débit prescrit en fonction du débit massique momentané, mesuré au niveau du débitmètre (4).
